About this 15.21ct lab-grown oval diamond

This 15.21ct lab-grown oval sits in the over five carat band, graded H colour (near-colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG739562186 or 739562186. Listed at 15 retailers as of October 29, 2026, with a 378% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
